Brain expression of NMDAR and AMPAR mRNAs in CPP-treated hamsters during torpor state. Effects of CPP (n = 4) on expression percentage (% ± s.e.m.) of (A) NR1 (white) and NR2A (grey) plus of (B) GluR1 (black) and GluR2 (black-white stripes) in some telencephalic and hypothalamic areas of hibernating hamsters were compared to controls (n = 4). AMPAR and NMDAR mRNA variations induced by CPP during torpor state were compared in the same manner to that of Figure 4. For abbreviations also check this Figure.
